We examined the impact of interviewees' language proficiencies on observers' lie detection performance. Observers (N = 132) were randomly assigned to make deception judgments about interviewees (N = 56) from Four proficiency groups (i.e., native, advanced, intermediate, and beginner English speakers). Discrimination between lie- and truth-tellers was poorest when observers judged beginner English speakers compared to interviewees from any other proficiency group. Observers were also less likely to exhibit a truth-bias toward nonnative than native English speakers. These results suggest that interviewing individuals in their nonnative languages can create inequalities in the justice system. (PsycINFO Database Record

This review of how dolphins are portrayed in popular media (including literature, film, television, and music) reveals four themes that may influence public acceptance of current scientific research into dolphin cognition. These themes are: (a) dolphin as peer to humans, of equal intelligence or at least capable of communicating with or helping humans; (b) the dolphin as the representation of a romantic notion of ideal freedom in nature, embodying principles of peace, harmony or love; (c) the dolphin as a naïve, innocent being that is subordinate and in need of human protection; and (d) the dolphin as superior to humans, potentially affiliating with a higher power or intelligence.This review revealed that the use of dolphins in humor reinforced or lampooned the four identified themes, indicating a common acceptance of these themes. The paper concludes with a discussion of the importance of considering popular narratives in the presentation of scientific research results.Many modern aquariums are striving to discover more effective methods to inform and educate their visitors about the lives of the marine mammals in their facilities. Dolphins, in particular, are a species with a high degree of public familiarity and desirability as a display animal. Aquariums have used

We examined how observers’ impressions of nonnative speakers and their cues to deception affected decision-making. Native and nonnative English speakers lied or told the truth about having committed a transgression, and then observers attempted to detect their lies. Observers were better able to discriminate between lie- and truth-telling native speakers than nonnative speakers. They also held more positive impressions of native speakers than nonnative speakers. Unlike observers, trained coders identified a multitude of differences in interviewees’ presentation of cues to deception across proficiency groups. Overall, nonnative speakers appear to be at a significant disadvantage in lie-detection contexts.
